No, unless you want to be a metrosexual, which most girls actually don't want anyway. Read Self-Made Man by Norah Vincent and you'll see that what most girls say and what they actually want are two different things. Perhaps this should also go in the girls are evil forum.

It's not weird to write a poem for a girl you like. I think it's actually sweet. G'luck there! At least you're telling her you like/love her in a very artistic manner. Poems can be symbolic or in free verse so don't fret about making things rhyme. As long as it comes from the heart, that's the most important part.
